Shimano RT-EM600 Disc Brake Rotor

• Centerlock interface uses a lockring to mount the disc rotor to the hub
• Centerlock rotors are interchangeable with all Shimano disc brakes as long as the hubs and rotor size match the caliper
• Unless otherwise noted, Centerlock rotors includes lock ring and washer
• Ice Tech brake rotors (RT-98; RT-81; RT-67) feature an aluminum core clad with stainless steel braking surfaces. The innovative design sheds weight, dissipates heat, and dramatically improves overall performance
• Freeza Technology (RT-99) features 3-layer structure with an aluminum core and stainless steel outer layers and additional aluminum cooling fins reduce rotor surface temperature by approximately 150 degrees Celsius compared to all-steel rotors
